To find the angle in radians, we need to convert the given angle from degrees to radians. We know that 180 degrees = π radians.

So,

34 degrees = (34/180) * π radians

= 0.1885 * 3.14

= 0.591 radians

Therefore, the answer is (C) 0.59 radians.

The area of the sector (the slice you eat) can be calculated using the formula:

Area = (n/360) * πr^2

where n is the central angle in degrees, and r is the radius of the slice.

Plugging in the given values, we get:

Area = (34/360) * 3.14 * 8^2

= 0.1 * 3.14 * 64

= 20.096 square inches

Rounding to the nearest tenth, the answer is 20.1 square inches.

The arc length of the pizza you have eaten can be calculated using the formula:

Arc Length = (2πr * Ø)/360

where Ø is the angle in degrees, and r is the radius of the slice.

Plugging in the given values, we get:

Arc Length = (2 * 3.14 * 8 * 34)/360

= 4.776 inches

Therefore, the answer is 4.776 inches.

The solution yn+1 is always less than or equal to yn, which means that the solution is stable for a < 0. Therefore the solution is of trapezoidal method.

The model problem (4.3) with a real constant a < 0 is given by:
[tex]y' = ay, y(0) = 1[/tex]
The trapezoidal method is given by:
[tex]yn+1 = yn + (h/2)(f(tn, yn) + f(tn+1, yn+1))[/tex]
where h is the step size, tn and yn are the current time and solution values, and  [tex]f(t, y) = ay[/tex]  is the right-hand side of the model problem.

To show that the solution of the trapezoidal method is stable for a < 0, we can substitute the right-hand side into the trapezoidal method and solve for yn+1:
[tex]yn+1 = yn + (h/2)(ayn + ayn+1)yn+1 - (h/2)ayn+1 = yn + (h/2)aynyn+1(1 - (h/2)a) = yn(1 + (h/2)a)yn+1 = yn(1 + (h/2)a)/(1 - (h/2)a)[/tex]

Answer:

the answer is (A) 21-1/2.

Step-by-step explanation:

First, we need to calculate the rate of descent in feet per mile:

750 ft / 3 miles = 250 ft/mile

Next, we can set up a proportion to solve for the distance traveled:

(distance traveled) / (total altitude change) = (distance traveled) / (altitude change due to descent) + (altitude at which descent begins)

Let m be the distance traveled:

m / (32000 ft - 16000 ft) = m / (250 ft/mile * x miles) + 16000 ft

where x is the number of miles traveled when the pilot is 16000 ft above the ground.

Simplifying:

m / 16000 ft = m / (250 ft/mile * x miles) + 1

Multiplying both sides by 16000 ft:

m = m / (250 ft/mile * x miles) * 16000 ft + 16000 ft * 16000 ft

Multiplying both sides by (250 ft/mile * x miles):

m * (250 ft/mile * x miles) = m * 16000 ft + 16000 ft * (250 ft/mile * x miles)

Simplifying:

250 * x * m = 16000 * m + 4000 * x * m

Dividing both sides by m:

250 * x = 16000 + 4000 * x

Subtracting 4000 * x from both sides:

-3750 * x = -16000

Dividing both sides by -3750:

x = 4.266666... miles

Rounding to the nearest half mile gives us:

x ≈ 4.5 miles

Therefore, the answer is (A) 21-1/2.

According to simple interest, Patricio will have $537.50 in his savings account after 5 years.

To calculate the amount of money Patricio will have in his savings account after 5 years, we can use the formula for simple interest, which is I = prt. "I" stands for the amount of interest earned, "p" stands for the principal amount deposited, "r" stands for the interest rate per year (as a decimal), and "t" stands for the time period in years.

In this case, the principal amount (p) is $500, the interest rate (r) is 1.5% or 0.015 as a decimal, and the time period (t) is 5 years. Using the formula I = prt, we can calculate the amount of interest earned over 5 years:

I = prt

I = $500 x 0.015 x 5

I = $37.50

So, Patricio will earn $37.50 in simple interest over 5 years. To find out the total amount of money he will have in his savings account after 5 years, we simply add the interest earned to the principal amount:

Total amount = Principal amount + Interest earned

Total amount = $500 + $37.50

The probability of the complement of choosing an orange juice box is 17/18. (option d)

The complement of an event is the probability of that event not occurring. In this case, the event is choosing an orange juice box, so the complement is choosing any other juice box (i.e., an apple juice box or a fruit punch juice box).

The total number of juice boxes in the cooler is:

4 + 8 + 6 = 18

The number of juice boxes that are not orange juice boxes is:

4 + 6 = 10

Therefore, the probability of choosing a juice box that is not an orange juice box (i.e., the complement of choosing an orange juice box) is:

10/18 = 5/9

But the question asks for the probability of the complement, which is the probability of not choosing a juice box that is not an orange juice box. This is simply:

1 - 5/9 = 4/9

However, the question asks for the probability of the complement of choosing an orange juice box, not the complement of not choosing an orange juice box. These two probabilities are equal, since the event and its complement always add up to 1. Therefore, the probability of the complement of choosing an orange juice box is:

1 - 8/18 = 10/18 = 17/18

Therefore, the probability of the complement of choosing an orange juice box is 17/18.

If P represents the number of pounds of your package, and C is the total cost of shipping your package, the equation that represents the relationship between P and C is C = 3 + 0.63P.

To write an equation that represents the relationship between the weight of the package (P) and the total cost of shipping (C), we need to use the information given in the problem. The shipping company charges a fixed base cost of $3 per package plus an additional $0.63 per pound.

We can represent the additional cost per pound as 0.63P, since the cost increases by $0.63 for every additional pound. Therefore, the equation that represents the relationship between P and C is:

C = 3 + 0.63P

This equation gives us the total cost of shipping a package based on its weight. We can use this equation to calculate the cost of shipping a package of any weight by simply plugging in the weight (in pounds) for P and then solving for C.

For example, if a package weighs 5 pounds, we can substitute P = 5 into the equation to get:

C = 3 + 0.63(5)

C = 3 + 3.15

in triangle TRS, it is an isosceles triangle with TS congruent to RS. So, angle T congruent to angle r. So, the angle is 63.

Therefore, the ladder touches the house at a height of 28 feet above the ground.

A triangle is a geometric shape that consists of three straight sides and three angles. It is a polygon with three sides. The sides of a triangle are connected by its vertices or corners. The triangle is one of the simplest and most fundamental shapes in geometry, and it has many important properties and applications. Triangles have many practical applications in everyday life and in various fields, such as architecture, engineering, and physics. The study of triangles and their properties is an important part of mathematics and geometry.

Here,

We can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the legs (the two shorter sides) is equal to the square of the length of the hypotenuse (the longest side, which is opposite the right angle). In this problem, the ladder, the side of the house, and the ground form a right triangle. The ladder is the hypotenuse, the distance from the house to the ladder is one leg, and the height we want to find is the other leg.

Let x be the height above the ground where the ladder touches the house. Then, using the Pythagorean theorem, we have:

x² + 21² = 35²

Simplifying and solving for x, we get:

x² + 441 = 1225

The region is a triangle with vertices at (0, 4), (1, 5), and (5, 0).

To find the area of the triangle, we can use the formula for the area of a triangle:

Area = (1/2) * base * height

The base of the triangle is the distance between the points (0, 4) and (5, 0), which is 5.

The height of the triangle is the distance between the point (1, 5) and the line 5 = x + y. We can find the equation of the line perpendicular to 5 = x + y and passing through (1, 5). This line has a slope of 1 and passes through (1, 5), so its equation is y = x + 4. We can find the intersection of this line and the line 5 = x + y by solving the system of equations:

y = x + 4

y = 5 - x

Substituting y = x + 4 into the second equation, we get:

x + 4 = 5 - x

Solving for x, we get:

If a person tosses a coin 9 times, there are 84 ways in which a person can get 6 heads in 9 coin tosses.

When a person tosses a coin 9 times, there are two possible outcomes for each toss - either heads or tails. Hence, there are a total of 2^9 = 512 possible outcomes for 9 coin tosses.

To find the number of ways in which a person can get 6 heads, we need to consider the number of ways in which 6 heads can occur in the 9 coin tosses, while the remaining 3 tosses can result in tails. The number of ways in which 6 heads can occur in 9 tosses is given by the binomial coefficient C(9,6), which is equal to 84.

Hence, there are 84 ways in which a person can get 6 heads in 9 coin tosses. This can be calculated using the formula for binomial coefficients:

C(9,6) = 9!/(6!3!) = (987)/(321) = 84

Alternatively, we can also calculate this using a combination of multiplication and addition. We can choose any 6 out of the 9 coin tosses to result in heads, which can be done in C(9,6) ways.

For each of these ways, the remaining 3 coin tosses will result in tails, which can occur in only one way. Hence, the total number of ways in which a person can get 6 heads in 9 coin tosses is given by:

Number of ways = C(9,6) * 1 = 84 * 1 = 84

Therefore , the solution of the given problem of equation comes out to be the first plant makes 5x + 22 more items per day.

Mathematical formulas frequently employ same variable word to guarantee agreement between two claims. Many academic numbers are shown to be equal using mathematical expression, also known as assertions. In this case, the normalise method adds b + 6 to employ the example of y + 6 rather than splitting 12 into two parts. It is possible to determine the length of the line and the quantity of connections between each sign's constituents. The significance of a symbol usually contradicts itself.

Here,

The first plant cranks out 8x + 15 items every day, while the second cranks out 3x - 7 items every day. By deducting the daily output of the second plant from the daily output of the first plant, we can determine how many more items the first plant creates than the second plant:

=> (8x + 15) - (3x - 7) (3x - 7)

If we condense this phrase, we get:

=> 8x + 15 - 3x + 7

Combining related words gives us:

=> 5x + 22

Therefore, compared to the second plant, the first plant makes 5x + 22 more items per day.

We can sketch the graph of 2x²+4x.

We can start by dissecting the equation and identifying its main components before drawing the graph of 2x²+4x.

The formula reads as y = ax² + bx + c, where a = 2, b = 4, and c = 0. It is a quadratic function.

The upward opening of the graph is indicated by the positive coefficient of x2 (a). By applying the formula -b/2a, which in this case equals -4/4 = -1, one can determine the vertex of the parabola.

Hence, the parabola's vertex is located at (-1,0).

By setting y = 0 and solving for x, we may get the graph's x-intercepts:

0 = 2x² + 4x

0 = 2x(x + 2)

Hence the x-intercepts are at x = 0 and x = -2.

We can set x = 0 to determine the graph's y-intercept:

y = 2(0)² + 4(0) = 0

The y-intercept is therefore at (0,0).

Using this knowledge, we can draw the 2x²+4x graph as follows:

Vertex located at (-1,0).

x = 0 and x = -2 are the two x-intercepts.

Y-intercept is located at (0,0).

For 5 years, n = 1, t = 5 years, r = 4% p.a.

CI = 1000[1+(4/100)]^(1×5)

CI = 1000[1+(1/25)]^5

CI = 1000×(26/25)^5

CI = 1000×1.21665

CI = $1216.65

For $2000 that was deposited during college graduation after 4 years,

The total number of years elapsed = 5 years + 4 years = 9 years

n = 1, t = 9 years, r = 4% p.a.

CI = 2000[1+(4/100)]^(1×9)

CI = 2000[1+(1/25)]^9

CI = 2000×(26/25)^9

CI = 2000×1.4233

CI = $2846.62

Therefore, the total amount (A) is $1216.65 + $2846.62 ⇒ $4063.27.

As a result, we are unable to further simplify the phrase. The final solution is (35 + 15 - x) / N, where x is the proportion of students who are proficient in both instruments.

We must first ascertain the total number of students in the band in order to calculate the percentage of those who play the flute or clarinet. Let's assume that N kids make up the entire band.

The total number of pupils who play either the clarinet or the flute is then calculated as follows: 35 + 15 - x

The percentage of band students who play either the flute or the clarinet is now (35 + 15 - x) / N, and we need to know what x's value is. Nevertheless, the problem does not provide this information.

When x is the subject of the formula a/b = 2x/x+5, the value of x = 5a/(2b - a).

The alphabetic letter that conveys a numerical value or a number is known as a variable in mathematics. A variable is used to represent an unknown quantity in algebraic equations.

Any alphabet from a to z can be used for these variables. Most frequently, the variables "a," "b," "c," "x," "y," and "z" are utilised in equations. By performing mathematical operations on variables as if they were express numbers, one is able to handle a variety of problems in a single computation. A quadratic recipe is a common example that demonstrates how to explain each quadratic condition by simply substituting the numerical estimates of the condition's coefficients for the variables that correspond to it.

The given formula is:

a/b = 2x/x+5

To make x the subject of the formula we have to isolate the value of x.

Using cross multiplication we have:

a(x + 5) = b(2x)

ax + 5a = 2bx

5a = 2bx - ax

5a = x (2b - a)

5a/(2b - a) = x

Hence, when x is the subject of the formula a/b = 2x/x+5, the value of x = 5a/(2b - a).

It takes Martha `4` hours to knit each hat and `13` hours to knit each pair of mittens.

What is meant by hours?

Hours are a unit of time used to measure the duration of an event or activity. An hour is equal to 60 minutes or 3,600 seconds. It is often used to indicate the time of day or to schedule appointments or events.

What is a pair?

A pair is a set of two things that go together or belong together, like a pair of shoes, socks, or gloves. It can also refer to a pair, a duo, or a twosome.

According to the given question

Let's assume that each hat takes `h` hours to knit and each pair of mittens takes `m` hours to knit.

From the given information, we know that:

- 3 hats and 3 pairs of mittens took a total of 51 hours. This means that 3h + 3m = 51.

- 3 hats and 5 pairs of mittens took a total of 77 hours. This means that 3h + 5m = 77.

We can use these two equations to solve for `h` and `m`.

First, let's solve for `h` by multiplying the first equation by 5 and the second equation by 3, and then subtracting the second equation from the first:

15h + 15m = 255

9h + 15m = 231

-----------------

6h = 24

h = 4

So each hat takes Martha `4` hours to knit.

Now we can use either of the original equations to solve for `m`. Let's use the first one:

3h + 3m = 51

3(4) + 3m = 51

12 + 3m = 51

3m = 39

m = 13

So each pair of mittens takes Martha `13` hours to knit.

Answer:

25 I am not sure

Step-by-step explanation:

The proportion of at-home games that were wins is 0.33, or 33%.

The proportion of at-home games that were wins can be found by dividing the number of at-home wins by the number of at-home games. This can be represented as a fraction:

At-home wins / At-home games

Using the information given in the question, we can plug in the values for at-home wins and at-home games:

0.20 / 0.60

Simplifying the fraction gives us:

1/3

Converting this to a decimal gives us:

0.33

Therefore, the proportion of at-home games that were wins is 0.33, or 33%.

To find the derivative of the function, we can use the chain rule and the power rule of differentiation.

What is chain rule?

The chain rule is a formula used to find the derivative of a composite function. If y = f(g(x)), then as per chain rule the instantaneous rate of change of function ‘f’ relative to ‘g’ and ‘g’ relative to x  results in an instantaneous rate of change of ‘f’ with respect to ‘x’

Let u = x² - 3, then we can rewrite the function as:

f(x) = [tex](u^{7})^\frac{1}{2}[/tex]

Using the chain rule and the power rule, we have:

f'(x) = (1/2) x (u^7)^(-1/2) x 7u^6 x 2x

Simplifying this expression, we get:

f'(x) = 7x(u^6) / (2(u^7)^(1/2))

Now, we can substitute x = -2 into this expression to find f'(-2):

f'(-2) = 7(-2)((-2)^2 - 3)^6 / (2(((-2)^2 - 3)^7)^(1/2))

Simplifying this expression, we get:

f'(-2) = -168/(2sqrt(19)^7) = -12.77 (rounded to two decimal places)

Therefore, f'(-2) = -12.77.
